Disable Annoying Low Disk Space Warning in Windows 7 & Vista

When your computer’s hard disk drive is nearly out of free space, Windows will warn you with a little pop-up box at regular intervals.This low disk space warning can be handy the first time but that’s usually where the usefulness stops.Aside from being annoying, Windows constant check for low hard disk drive space uses system resources which can slow Windows down.
